REPEATlNG-WATC H.

SPECIFICATIQN forming part of Letters Patent No. 325,854, dated September 8, 1885.

Application filed March 7, 1884.

To all whom it may concern;

Be it known that we, CHARLES MoRLE'r and EUGENE DUPUIs, both of the city, county, and State of New York, have invented a new and Improved Repeating-Watch, of which the following is a full, clear, and exact description.

This invention relatesto certain new and useful improvements in that class of watches known as repeatingwatches, and which are provided with mechanism for striking bells, wires, or metal plates in such a manner as to indicate the time by a number of strokes for the hours and a number of strokes for the minutes.

The object of our invention is to materially simplify the construction of such repeatingwatches, whereby fewer parts are required, the striking mechanism can be driven from the mainspring 0f the watch, the striking mechanism can easily be removed from the watch, and the cost of these watches will be materially reduced.

Theinvention consists in the combination, with a watch, of a repeating mechanism and means for operating the repeating mechanism from the mainspring of the watch.

The invention further consists in the combination, with a watch and the repeating mechanism, of means for throwing the repeating mechanism in gear with the mainspring at the same time that the repeating mechanism is started. 7

The invention further consists in various parts and details and numerous combinations of the same, as will be fully described, and set forth hereinafter. I

Reference is to be had to the accompanying drawings, forming part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure l is a face view of our improved striking mechanism for a repeating-watch. Fig. 2 is a face view of the detachable plate carrying the striking mechanism, parts of the mechanism being omitted to show other parts more clearly. Fig. 8 is an inside view of the plate below the one carrying the repeating mechanism. Fig. 4 is a face view of the plate directly below the dial, showing the winding the clock-work on the broken line 00 as m 00 a0 00,

mechanism and the mechanism for connecting (No model.)

the mainspring with the repeating device,,

parts being broken out and others shown in section. Fig. 5 is a crosssectional view of Fig. 1. Fig. 6 is a cross-section 011 the line y 3 y, Fig. 1. Fig. 7 is a sectional view on the line w w, Fig. 1. Fig. 8 is a plan view of the under side of the wheel for. operating the middle spindle.

Referring to Fig. 4, a beveled pinion, A, is mounted on the windingstem A and engages with the beveled cog-wheel A which engages with the cogwheel A adapted to engage with a cog-wheel, B, on the casing, in which the free end of the mainspring is fastened.

A pivoted pawl, B, is adapted to engage with the cogs of the wheel B, and is pressed against the said cogs or teeth by a spring, B, resting on the outer edge of the pawl. The said pawl is provided with a shoulder, B against which the end of the spring B can rest under certain, circumstances, as will be described hereinafter. The pawl B is pro: vided with a projection, B, against the inner edge of which a sliding pin, B rests, the opposite end of which pin is beveled and adapted to pass in between the cogs of the wheel A", the said pin being adapted to slide in a suitable guide aperture in the frame ofthe watch. The pawl B is also provided with a projection, B, which is adapted to act on one end of a pivoted lever, G, the opposite end,O,of which rests against a hub or spindle, A, 011 which the cog-wheel A turns. A suitable spring is provided for pressing the wheel A against the rim of the wheel B on the spring-casing, as is usual in stem-winding watches.

A push-pin, D, projects from. the edge of the works and is formed on the angle ofan angle spring-lever, D, that will be described hereinafter, and the said push-pin D also acts on the projectionB" of the pawl-lever B; and if the said pushpin is pushed inward the end disengaged from the teeth of the wheel 13, as shown. If the pawl-lever is moved inward by the push-pin, as described, its projection B will act on the end of the lever G and cause the opposite end,G, of the said lever C to press on the hub A of the wheel A and move the wheel A from the wheel B, whereby the said wheels A and B will be disengaged and will remain so as the pawl B is locked in position by the spring B". At the same time the beveled end of the bolt or pin 13 is moved in besnapping over the shoulder B and resting rounded or beveled end of an upright shaft on the edge of the pawl lever above the shoulder.

By the above-described movement of the PIIWl-l'GX'Ql B the end of the lever G is released, thus permitting the spring provided for this purpose to throw the wheel A in gear with the wheel B, and thus permitting the spring to be wound by turning the winding-stem A, which turns the pinion A, the beveled cogwheel A the cog-wheel A, and the cog-wheel B. It is thus seen that as soon as the pushpin D is pushed inward the mainspring is dis engaged from the winding device, and as soon as the winding-stem A is turned, the winding apparatus is thrown in gear with the mainspring.

As stated above, the push-pin D is formed at the angle of an angular spring-lever, D, secured on the inner surface of a plate, D the free end D of the said spring being beveled and resting on a bridge, D, held on the under side of the plate D The lower slightly or spindle, E, rests on the bridge D", and passes through the plate D and on the said shaft E is loosely mounted a sleeve, a, on which is loosely mounted a cog'wheel, F, and on a sleeve, a, held to turn with the shaft or spindle E, is rigidly mounted a wheel, G, provided with twelve teeth, G, which occupy about onethird of the circumference of said wheel.

Above the wheel G a pinion, J, is' rigidly mounted 011 the sleeve a, and above the pinion J a curved arm, I, is loosely mounted on the shaft E, and is connected by a pin or rivet, I, with the pinion J. the shaft E, which is of less diameter than the lower part, passes through an aperture in the free end of a spring, E", which is secured on the plate D, the free end of the said spring E resting on the shoulder formed on the upper end of the shaft E.

The wheel G is provided at its under side The upper end, B, of

with a downwardly-projecting tooth, G adapted to pass in between and engage with the teeth of the cog-wheel F. The cog-wheel F engages with the cog-wheel F, driven by the mains iiring-spindle f. The cog-wheel F en gages with a pinion, F", made integral with another cog-wheel, F", engaging with a pinion, F, made integral with a eog-whecl, F engaging with a pinion, F, provided with an escapement-wheel, F which engages with an anchor, F", on which a swinging weighted arm, F, is mounted, as shown in Figs. 1 and 7. The pinions F", F, and F and anchor F are not mounted on arbors held between two plates or bridges, as is usual in watches, but are mounted on pivots f, projecting upward from the plate D".

The object of the train of gearing just described is to prevent the wheel F from revolving too rapidly, as will be fully set forth hereinafter.

On two spindles, h and h, projecting from the surface of the plate D two stepped or toothed cams, H and H, are mounted, the said stepped cams gradually increasing in diameter from the first to the last step. On the spindle h is rigidly mounted a starwheel, H having eleven teeth, and the stepped cam H is provided on its under side with a tooth, h, adapted to act on the teeth of the starwheel H", so that for every revolution of the steppedeam H the stepped eam H will be moved one'eleventh ofa revolution. A locking-spring, H", is secured 011 the plate D and IOC its free end rests against the teeth of the starwheel H to hold the said wheel in place.

Two curved arms, J and J, rigidly united and held almost parallel, are both pivoted on a spindle, j, the curved arm J having a rack, J formed in one edge at its free end, and the said rack being adapted to engage with the teeth of the pinion J, which is mounted rigidly on the sleeve a of the spindle or shaft E. A prong, J", formed at the free end of the arm J'-, is adapted to rest on the steps of the stepped or toothed cam H.

An elliptical or like frame, K, is pivoted on a spindle or pivot, 7r, and is provided with a rack, K, having eleven teeth, which rack is arranged almost diametrically opposite the spindle or pivot k. The said frame K is also provided witha prong, K, the end of which is adapted to rest on the steps of the toothed or stepped cam H. The frame K is provided with a shoulder, K against which the free end of the arm I is adapted to rest. A stoppin, Z, projects down from the under surface of the frame K, and is adapted to strike against a pin, m, projecting upward from the surface of the plate A spring, L, secured at one end on the plate D', has its opposite end connected with the arm Jashort distance from the pivot or pintle 9', so that the spring will have the tendency to throw the arms J J in the directi on of the arrow w. A spring, M, having one end secured on the plate D, hasits free end resting against a pin secured on the frame K a short distance from the pivot 70, which spring M has the tendency to throw the frame K in the direction of the arrow y. Two circular spring-wires, N and 0, each have one end secured on the plate D as shown at 0, Fig. 1. Two hammers, Nand O, are pivoted to the plate D Aspring, P, acts on the hammer N, at that end opposite the one provided with ahead,and presses the said end of the hammer against the stud P on the plate D, thereby pressing the head in the direction toward the corresponding spring, N. A spring, Q, acts on the hammer Oand presses its head in the direction toward the spring 0, and presses the opposite end of the said hammer 0 against the stud Q on the plate D The hammer O is provided at the end opp0- site the one with a head with a projection, B, against which the teeth G of the wheel G can act. The hammer Nis provided with a tooth, S, against which the teeth of the rack K of the frame K can act. The hammer 0 serves to strike the number of hours on the spring O, and the hammer N serves to strike the minutes on the spring N. The hammer N does not indicate each single minute; but each stroke corresponds to five minutes.

The operation is as follows: If the push-pin D is pushed inward and pushes the springlever D inward, the beveled end D of the said lever D, acting 011 the spindle E, pushes the same upward, whereby the wheel G will be raised, and the tooth G on the under side of the said wheel G will be disengaged from the teeth of the wheel F, thus permitting the springs M and L to throw the frame K in the direction of the arrow 3 andthe arms J and J in the direction of the arrow :0,- bnt the prongs K and J of the frame K and the arm J", respectively, strike against the steps of the cams H and H, thereby checking the movements of the frame K and the arms J J By the movement in the direction of the arrow or of the arm J, its rack J revolves the pinion J, and thereby turns the wheel G, connected with the pinion J, in direction of the arrow to. The cams H and H are operated by the clock mechanism, the cam H making one rev olution every hour and the cam H one revo lution every twelve hours. It is evident that at different times of the day the cams H and H are in different positions in relation to each other and to the ends of the prongs J and K". Thus at twelve oclock that edge of the cam H the shortest distance from the pivot h will face the end of the prong J", thus requiring the arms J and J to move a greater distance before the end of the prong J rests against the edge of the cam H. At or near the end of the hour the cam H is in such a position that that part of its edge which is the shortest distance from the pivot h will face the prong K of the frame K, thus requiring a greater movement of the frame K in the direction of the arrow 3 to cause the end of the prong K to rest 011 the edge of the cam H. At one or two oelock the movement required to bring the prong J against the edge of the cam H will be least, and the throw of the arm J will be correspondingly small. A few minutes a'tcr the hour the distance between the edge of the cam H and the end of the prong K will be least, and the distance that the prong K must move to come in contact with the edge of the cam H will be least, and the throw of the frame K will be decreased in proportion. limit the throw of the frame K and the arms J and J, according to the time. If the frame K, for instance, is thrown but a short distance in the direction of the arrow 3 and moves back in the inverse direction of the arrow y, but a few teeth of the rack K will strike against the tooth S of the hammer N, and the hammer will strike but a few times. If the throw of the frame K in the direction of the arrow y is very great, more teeth of the rack K will strike against the tooth S of the hammer, which strikes the spring-wire N oftener. In a like manner, the number of times that the hammer O strikes the spring-wire O is governed by the distance that the prong J must move to come in contact with the rim of the cam H. After the pin D has been pushed inward the springlever D snaps outward and from under the lower end of the spindle E, thus permitting the spring E to force the spindle E downward and engage the tooth G of the wheel G with the teeth of the cog-wheel F again. As has been stated, by pushing the push-pin D inward the pawl B is disengaged from the ratchet-wheel B, which is mounted on the arbor or spindle to which the mainspring is fastened, thus permitting the spring to revolve the said wheel in the inverse direction of that in which it is revolved by winding the'spring. The spring is then held at the rim of the springcasing and acts on the central spindle, thereby also revolving the wheel F. If the pawl Thus the cams H and H always IIO B should not be disengaged from the wheel B,

which prevents the spring from revolving the wheel F" too rapidly. The wheel F, if revolved from the spring-spindle, revolves the wheel F in the inverse direction of the arrow w,- and as the tooth G connects the wheel G with the wheel F the said wheel G will also be revolved in the inverse direction of the arrow 20, and its teeth G will successively strike against the tooth R of the hammer O, causing the hammer to strike the wire 0, and thus produce the desired sound. By the movement of the wheel Gin the direction of the arrow 10 the free end of the arm I has been moved a greater or less distance from the shoulder K of the frame K, and by the time that the last tooth, G, has

acted on the tooth R of the hammer O the end of the arm I will rest against the shoulder K of the frame K; and as the wheel G continues to move in the inverse direction of the arrow to the frame K will be moved in the direction of the arrow 3 and the teeth of the rack K will strike against the tooth S of the hammer N, and thus cause the hammer N to strike the wire N, each stroke corresponding to five minutes past the hour. The frame K moves in the inverse direction of the arrow y until its pin Zstrikes against the pin m on the plate D whereby the entire ringing mechanism or repeating mechanism is stopped automatically. As soon as the winding-stem is turned the wheel A is thrown in gear with the wheel B, and the pawl B is engaged with the ratchct-wheel B, thus preventing the spring from acting on the central spindle and revolving the same, and now the spring must act on the rim of its casing, as the central spindle is held by thepawl B, which engages with the ratchet-wheel B.

That I may be fully understood I will repeat the action in brief. By pressing the push-pin D inward the cog-wheel B, connected with the spindle 011 which the mainspring is fastened, is released, and at the same time the wheel G is disengaged from the ratchetwheel F, permitting the frame K and the arms J J 2 to be thrown back until their prongs J and K rest against the teeth of the cams H and H. The mainspring can now revolve its central spindle or stem as the wheel B is released, and the said mainspring can revolve the wheel F and the wheel G, thereby causing the teeth G of the wheel G to operate the hammer O; and when the hammer O has completed striking the hours, the arm I rests against the shoulder K of the frame K and moves the frame K in the inverse direction of the arrow 3 and causes the teeth of its rack K to act 'on the hammer N, causing the same to strike the spriug-wire N until the pin Z rests against the pin m.

In place of providing the tooth G on the under side of the wheel G in such a manner that it can engage with the teeth ofthe wheel F, the tooth G can be arranged in a different manner, and can be adapted to pass into a recess or aperture in the upper surface of the wheel F.

Heretofore repeating watches have been provided with separate springs for operating the repeating mechanism; but in our improved repeatingwatch the mainspring is used for operating the repeating mechanism, and the means which have been described above are used for operating the repeating mechanism from the central spindle of the mainspring, the usual clock-work mechanism being operated from the outerend of the mainsprin g, which acts on the casing of the mainspring. Furthermore, theentire repeating mechanism is held on the plate Diwhich caneasily be de tached, so that the other parts of the works need not be disturbed while removing the striking or repeating mechanism, and at the same time that the repeating mechanism is thrown back by its springs into the position corresponding to the hour and minute the connection of the mainspring and repeating mechanism is made.

Having thus fully described our invention,

we claim as new and desire to secure by Letters Patent 1. The combination, with a watch, of a repeating mechanism, gearing for operating the repeating mechanism from the mainspring, and mechanism, substantially as set forth, for disengaging the ratchet-wheel on the spindle of the mainspring from its pawl in the opera tion of starting the repeating mechanism, substantially as herein shown and described.
